perfSONAR User Q&A and Other Discussion

[Zhi-Wei Lu <>]

Hi all,

 

We have a few perfsonar nodes and we configure band width tests between them.  Let us call hosts A and B,  on both hosts we configured BW test between them.  On host A, we see throughput between A and B on both direction, however, on host B, I only see GUI display of Src-Dst, not Dst-Src throughput.  We did change the FQDN of host B (kept the same IP), the old name is a CNAME to the new FQDN for host B.

 

If I manually run “bwctl -s A” and ”bwctl –c A”  from host B, the tests work just fine. It appears that the data in the database table appears to be just fine (bwctl.201409_DATA). 

 

Thank you for your suggestions to fix this issue.
